Why Chatbots Need NLP?

AI has brought tremenduous improvement in the world of technology. NLP is one of the major branch in AI. Natural language processing (NLP) is the ability of a machine to analyze, understand, and generate human speech. The main purpose of NLP is to give bot a personality. It also helps in filling the gap between human communication and computer understanding. Its main objective is to let a bot understand conversation in a better way.

The first step to NLP is understanding and then to generate responses accordingly. NLP can be divided into two parts further: NLU (Natural Language Understanding) and NLG (Natural Language Generation).

NLU helps in understanding the meaning of given text. And, for understanding structure, NLU tries to resolve ambiguity present in natural language. And, NLG is responsible for producing text from structured data in a readable format with meaningful phrases and sentences. With the use of lexicon and a set of grammar rules, a NLG system can form complete sentences.

First, computers convert natural language into artificial language, which is known as speech recognition. This is done by NLU. Once the information is in text form, NLU helps in understanding the meaning of that text. By the end of the process, the computer should understand the meaning of what is said or expressed.

NLP is something which provides a personality to your bot it adds some intelligence to the chatbot. It gives it a superpower to reply and understand like humans. It allows the bot to answer common questions, for example, "how are you? "

One can also ask weather details by asking about the weather of a place in Celsius or Fahrenheit. Now, it will help in giving the weather details in a one-line sentence. NLP also plays a crucial role here.

For instance, Suppose a person is having a conversation with a bot and are just selecting options one after another being served by the bot obviously he/she will get bored.

Also, now, suppose rather than simply providing with options it takes the floor and asks a question to learn more about the person's requirements, it would be much better. It will be similar to have a conversation with a human. This is the point where NLP comes into a role, its whole motto is to make the bot smart.

NLP technology will continue to gain momentum. Organizations around the world will need to be ready to benefit from NLP's presence. NLP endeavors to bridge the gap between machines and people by enabling a computer to analyze what a user said (input speech recognition) and process what the user meant. So, NLP is of a vital importance in the business world and our lives.
